Chinese supercomputer is the world's fastest — and without using US chips

A Chinese supercomputer built using domestic chip technology has been declared the world's fastest. The news highlights China's recent advances in the creation of such systems, as well the country's waning reliance on US semiconductor technology. The Sunway TaihuLight takes the top spot from previous record-holder Tianhe-2 (also located in China), and more than triples the latter's speed. The new number one is capable of performing some 93 quadrillion calculations per second (otherwise known as petaflops) and is roughly five times more powerful than the speediest US system, which is now ranked third worldwide.
